Hello! I am having the same issue with verifying my phone number after updating some info on my account. I have logged in on two different browsers, on two different computers, and I have used two different phone numbers each time. I am putting my number in with the area code and without any dashes but not receiving the verification message.
oooh boy. What a day in the forum.
So many thoughts here but cannot say.
It seems Upwork no longer accepts internets numbers. Would you say you probably tried to use something like Google Voice? Would that be a close assumption?
